Recently, our research group was invited to publish a review article on ion migration in hydrides.

Hydrides are hydrogen/energy carriers with potential applications in chemical conversion, hydrogen storage, heat storage, ion conductivity, etc.The radius of the H^- ion of hydrides is close to that of O₂^-, but they have less charge, special coordination, and are easy to polarize. These structural characteristics enable some hydrides to conduct Li⁺, Na⁺, Mg₂⁺, and H^-. In this review, the authors summarize the research progress of these ions in hydride conduction, explain the design and optimization of ion conduction strategies, and discuss the advantages and disadvantages of hydrides in solid electrolytes, ultrafast ion conductors, etc.

This review articlewas published in Trends in Chemistry under the title of "Ion Migration in Hydride Materials". The first authors of this work are Yu Yang, an Associate Professor in our group, and Zhang Weijin, a postdoctoral fellow. This work was supported by the National Key R&D Program, the National Natural Science Foundation of China, and other projects. (Text/Photo by Yu Yang)
